Jade, 24, recently teased details of their upcoming documentary, which they have been working on since November last year, saying the footage will be "really surprising" for their fans.

Asked how things are going, she told BANG Showbiz: "We've got a few new tracks from the album. We did a documentary which is really exciting for us and is something we have always wanted to do to show an insight into our lives, so it's going to be really surprising for the fans."

While Jesy previously revealed how much the girls wanted to a document, saying: "We are in talks at the moment. We really want to do a documentary as we feel people do not know much about us.

"They know our songs and have seen us perform but they don't know our personalities, so we would love to do a documentary.

"We want to get someone to follow us around on this whole tour for a whole year."
